Android Application "Source Not Found" java.lang.runtimeexception

I switched from running my app on a phone to a nexus 10 tablet and now it says "unfortunately the application has stopped."
The tablet is running 4.4.2, my target api is set to 19 in the manifest.
When I run it in debug mode I get Source Not Found. I tried clicking edit source lookup path and adding my project and had no luck.
I've looked all over the internet and haven't had any luck solving this problem. Any suggestions would be a big help.

If anyone can point me in the right direction it would be great. Thanks.

You are not allowed to do network communication on the UI main thread. This is to stop your code blocking the UI and it locking up. You need to do the network work on another thread. You should read about AsyncTasks:
http://www.vogella.com/tutorials/AndroidBackgroundProcessing/article.html#concurrency_asynchtask
http://developer.android.com/reference/android/os/AsyncTask.html

NetworkOnMainThreadException
This means that you cannot perform network operation in the main thread (like onClick or other methods not used in another thread).
Try to put the code in
public void onClick(View view) {...}
to an AsyncTask
AsyncTask

Trying to determine which interface it will lead after user login, but my mobile apps forced closed

When I click login it just attemping to login and forced closed my apps

What am I trying to do is that I used email and password as my login id and login password, once my login.php check database for the existing user and matching the input password is same with the password that saved in database. Once it matched, it will acquire the position value from database to Login.java to determine which interface it will go like User Main Menu and Staff Main Menu.
This is my database structure
CREATE TABLE user (
userid INT( 30 ) NOT NULL AUTO_INCREMENT ,
name VARCHAR( 100 ) NOT NULL ,
email VARCHAR( 50 ) NOT NULL ,
password VARCHAR( 20 ) NOT NULL ,
mobilenumber VARCHAR( 30 ) NOT NULL ,
address VARCHAR( 100 ) NOT NULL ,
city VARCHAR( 30 ) NOT NULL ,
postcode VARCHAR( 10 ) NOT NULL ,
state VARCHAR( 30 ) NOT NULL ,
position VARCHAR( 30 ) NULL ,
cardbalance VARCHAR( 10 ) NULL ,
PRIMARY KEY ( `userid` ) ,
UNIQUE (`email`)
) ENGINE = MYISAM
So, I'm not sure that the way I retrieve data is correct or not.. the position attribute is either user or staff.

Android Java IllegalStateException: Could not execute method of the activity

I'm trying to code a simple randomizer app. I had the randomizer button working, but then I changed some code (which I thought was irrelevant to the randomizer button) and it started crashing and getting the "IllegalStateException: Could not execute method of the activity" error. From what I can tell, this error is very specific to what the code is, because I could not find any answers that fit my code.
package com.example.randomgamechooser;

dbUtil.open();
String string = dbUtil.getRandomEntry();
//TextView textView = new TextView(this);
TextView textView = (TextView) findViewById(R.id.chosenbox);

Cursor is Null in Service Class - But Returns Value in Standalone Activity Class

My classmates and I are stuck on an issue with android application we are building.
We've successfully built an Android app which contains an activity which searches our browser histories / bookmarks for specific urls and launches another activity (successfully) if a match is found as an example of an adult content warning implementation.
This is functioning fine.
Now we are implementing a service class to continually execute every few seconds - in order to execute the search of our recent history using our new service class - but we're experiencing a few issues.
Our problem is when we attempt to add the "Nanny" source code from Nanny.java to the service class so the "Nanny" script will search the history continuously, instead of just once - the "Nanny" application continually force closes - due to a null pointer exception at the initialization of our cursor: if (cursor.moveToFirst()) {
Which is a bit strange because the NullPointerException does not occur when the exact same script is executed outside the service class in a test file we have (Main.java)
Our working Main.java and our working service class [which successfully displays a toast every few seconds] as well as our [failed] combination of the two - are shown below:
Empty Service Class:
public class Service_class extends Service {
#Override
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
return START_STICKY;
}
#Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(this, "Service Stopped", Toast.LENGTH_LONG).show();
}
#Override
public void onCreate() {
super.onCreate();
}
}

You are setting the cursor to null...
you use this method to instantiate the cursor:
Cursor cursor = managedQuery(android.provider.Browser.BOOKMARKS_URI,projection, null, null, null);
and then you define managedQuery() method like this:
private Cursor managedQuery(Uri bookmarksUri, String[] projection, Object object, Object object2, Object object3) {
// TODO Auto-generated method stub
return null;
}}
essentially what your code says is:
Cursor cursor = null;
curser.doSomething();
this will always result in a nullPointer. I strongly suggest you go back and study java fundamentals before diving in to android, you are just asking for headaches if you are trying to accomplish something in android with such a lack of understanding of java.
